In ordinary temperature some ceramic materials can absorb the environmental energy and radiate appropriate amount of far infrared ray with wavelength of 4 mum~14 mum. Far infrared ray with wavelength of 4 mum~14 mum can be absorbed by cell molecules of the living beings to cause resonance and activation. By utilizing this property, the slurry of the far infrared ceramic materials is coated with mum-grade thickness on some flexible base films to form the product of the present invention, and is used as as a wrappage, a protective lining, . . . etc., so as to achieve the freshkeeping for the food, the late-ripen for the picked fruits, as well as the warmkeeping, raising and healthkeeping for the living beings.
